How to test if a jQuery selectors condition is more than 2 times?

Question

Possible Duplicate:
Fire jQuery event on div change

I'm using this tiny plugin to watch for changes in the html: https://github.com/jacobrelkin/jquery-watcher

This works fine, the problem is I need the if condition to validate if it's over 2 times, reason being when the gallery loads and it shifts left and right creates the -moz-grabbing condition twice onload.

I tried doing

  if(  $('#gallery-1').has('div').css('cursor', '-moz-grabbing') > 2)
  if(  $('#gallery-1').has('div').css('cursor', '-moz-grabbing').length > 2)

I also tried putting it in a variable then doing > 2

None of the above seem to be working not sure what I'm doing wrong?

$('.sliderContainer').watch('innerHTML', function() {
    if(  $('#gallery-1').has('div').css('cursor', '-moz-grabbing') ) {
        console.log($('#gallery-1').has('div').css('cursor', '-moz-grabbing'));
        $('#collapse_content_1').toggleClass('collapse_inner_off');
    }
});

checking for a vendor prefix may not be the best idea... what if the user is using Chrome? — ahren, Nov 28 '12 at 22:11
I would look at the JavaScript that is causing the HTML to change. Looking at the end result isn't a good idea. — Blender, Nov 28 '12 at 22:11
That plugin is using polling with `setInterval(..., 700);`. Use it with caution or Try a different approach. — Selvakumar Arumugam, Nov 28 '12 at 22:13
@BrunoSousa I'm really looking to validate if the condition is met over 2 times — zadubz, Nov 28 '12 at 22:21

.css('cursor', '-moz-grabbing') actually sets the stylesheet rule. You probably want to use .filter:

$('#gallery-1').has('div').filter(function () {
   return $(this).css('cursor') == '-moz-grabbing';
}).length > 2

is that the if condition? sorry very new to jQuery – zadubz Nov 28 '12 at 22:27
Yes, you can put that in the `if ()` – Explosion Pills Nov 28 '12 at 22:28
unfortunately the .length > 2 isnt doing what its suppose to do, it still loads with the condition less than 2 times – zadubz Nov 28 '12 at 22:39
